Question

in the simulation, set the velocity to zero and observe the effect on the graphs. what happens to the position vs. time graph when the velocity is zero? the graph becomes a curve. the graph is a diagonal line. the graph is a straight, flat horizontal line. the graph fluctuates. 19/19 question 19

Explanation:

Step1: Recall relationship between velocity and position - time graph

The slope of a position - time graph gives the velocity. When velocity \(v = 0\), there is no change in position with time.

Step2: Analyze graph shape for zero - velocity

If the velocity is zero, the object is at rest. In a position - time graph, this is represented by a straight, flat horizontal line because the position does not change over time (\(\Delta x=0\) for \(\Delta t> 0\)), and the slope \(\frac{\Delta x}{\Delta t}=0\).

Answer:

The graph is a straight, flat horizontal line.
